MOLD OFi DIE. FOR HEEL-COMPRESSING MACHINES.

SPECIFICATION forming part of Letters Pa/tent No. 764,696, dated July12, 1904. Application filed December 21, T903. Serial No- 186,036. (Nomodel.)

To all whom, it TVbCl/y concern;

Be it known that I, (JOMFORTL. WHITING, a

citizen of the United States, residing at Brocle ton, in the county ofPlymouth and Commonwealth of Massachusetts, have invented certainImprovements in Molds or Dies for Heel- Compressing Machines, of whichthe follow ing description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention has for its object to provide means" for forming a novelheel, which is also of my invention, and which is described and claimedin my pending application, Serial No. 186,037, filed December 21, 1903.

The dies ordinarily used for compressing heels compriseapressure-plate,which acts on the tread-face of the heel, a follower orheel-v seat die,which acts on the seat, a breastplate, which acts on the breast, andradially-moving dies, which act on the side and rear portions of theheel. The seat of the heel is usually molded to fit the heel-seat end ofthe sole of the shoe, and the breast end of the seat is usually beveledduring the operation of compressing the heel, said bevel being formedinthe end of the seat, so that when the heel is being attached the portionthereof which is to be removed by the breastingoperation will not indentthe shank portion of the sole, as

such an indentation would show plainly after the heel had been breasted.

The diesheretofore used for compressing heels have proved unsatisfactorybecause they form a roughened projection on the heel at the edge formedby the junction of the breast and the beveled portion of the seat, whichroughened projection would be forced into the surface of the sole whenthe heel was being attached to the shoe, and would make an indentationthat would show plainly after the heel had been breasted. The reason forthe formation of this roughened projection on the heel is that it ispractically impossible in machines of this character, as they haveusually pressing operation.

always more or less space between these 00- plate and the end of the lipwith which the follower is provided for forming the bevel in the breastend of the seat of the heel, said breastplate and lip passing each otherin a substantially shearing action during the com- (Jonsequently' thereis acting faces, and as the follower is of the same size and outline asthe seat of the finished heel some of the leather in the heel will flowinto this space and form a roughened projection on the upper edge of thebreast end of the heel or thatiedge formed'by the junction of the breastand thebeveled portion of the seat. 1

The dies which embody my present invention preferably comprise apressure-plate, follower, breastplate, and radially-moving dies,although the most important feature of my invention has to do withtheshape of the follower or heel-seat die, which I have provided with means.for forming a rounded edge on the heel at the junction of the breastand seat, and so far as thisfeatureof my invention is concerned it. isnot material what construction or arrangement of the other parts beadopted. The follower is provided at its inner breast end with a lip01'' downwardly-projecting'portion for forming a bevel in the breast endof the heel, said lip being provided with an extended part whichprojects beyond the breast end of the heel and which is curved on itsunder surface, .so as to round off the upper edge of the breast where itjoins the beveled portion of the heel. The breastplate is provided witha recess to receive the extended part of the lip, and as this partprojects beyond the breast. end of the heel and extends downwardly thereis no liability of a roughened projection being formed on the heel atthe edge formed by the junction of the breast and beveled portion ofthe-seat.

- of the breast-plate.

throughout its body and will form a depression in the seat of the heelwithout causing a bulge to form on the tread-face of the heel, saiddepression being provided to receive the portion of the outer sole whichis forced outwardly by the shank or stiffener, which is, placed betweenthe inner and outer soles of Y the shoe.

Referring to the drawings, Figure 1 is a side 6 is a perspective view ofa portion of a heel that has been compressed in dies ordinarily,

used for this purpose and shows at 5 the roughened projection thatformed on the lower edge of the beveled portion during the cor'n- Byconstructing the follower in this manner pressing operation.

, In the drawings, Fig. 1 represents a portion of a heel=compressingmachine now in common use; but as this invention relates only to thecomptessing=dies it is not necessary to describe the mechanism of saidmachine.

2 lepresents the pres'suremlate; 4, the follower; 6, the breastplate,and 8 one of the dies which act on the side and rear portions of theheel. The follower has at its breast end adownwrtrdly-projeoting lip 10,which forms the desired bevel in the breast end of the seat of the heel,and said lip is provided with an extended part 12, which projects beyondthe breast end of the heel and also projects downwardly below the edgeof the lip. The underneath' surf'ace of the extended part of the lip iscurved, as shown in Figs. 2 and 5, so that when the follower and bottompl e are brought together in the operation of ompre'ssing a heel theheel held between them will be beveled at the breast end of the seat by-the lip 10', and the lower edge of the beveled portion will be roundedby the curved surface on the underneath'si'de of th'eextended part I2.The breastplate is provided with a recess 14, in which the extendedpartof the lip travels,and as said part overlaps the breast end of theheel and extends .d-ow'nwardiy there is no possibility of a roughenedprojection forming on the heel at the edge formed by the junction of thebreast and beveled portion 'of the seat, as has heretofore been usual,as shown in Fig. 6. The re- 14 in the breas'tplate extends downwardly inthe face of the brea'stplate for a greater distance than the length ofthe extended part 12 from the top to the lower edge thereof, so thatwhen the follower and bottom plate are closedtogether in theoperation'of compress-J ing a heel there will be a space between thelower edge of the extended part and the lower edge of the recess, asshown in Fig. 2. This 7 Fig. 5 is a sectional I view taken on the lineas w of Fig. 4, and'Fig.

space is provided to receive the leather that is displaced from the seatof the heel to form a depression therein for receiving the portion ofthe outer sole which is forced outwardly by the shank or stiffener,which is placed between the inner and outer soles. If the breastplatewere not provided with such a space or opening to receive the displacedleather, that part of the heel at the point where-the depression wasformed in the seat would be compressed to a greater degree than otherportions of the heel. In fact, the compression of the heel at this pointwould be so great that a bulge would form on the treadface of the heelsoon after it had been removed from the dies.

Asshown in Figs. 4 and 5, my improved follower is provided .with araised portion for forming said depression in the seat of the heel,

and this raised portion commences at about the center of the followerand slants gradually toward its breast end, the central part of theraised portion being substantially flat at 18.

and by providing the breastplate with the recess previously described,into which the-surplus leather may flow when a heel is being compressed,a uniform pressure. throughout the body of the heel is insured.Furthermore, there is no liability of a bulge forming on the tread-faceof the heel, as the leather that is displaced from the seat forms abulge at 20 (see Fig. 2) on the breast of the heel 22; but as the end ofthe heel is subsequently removed in the bre'asting operation the bulgeformed on the breast is not objectionable. It should beun'derstood thatthis feature of my invention is not limited to a recess formed in thebreastplate, as the location of such recess is not material so long asit is arranged to provide for a fl'owage of the leather of the heel incase of excessive pressure on the heel, thus not only insuringa uniformcompression throughout each heel, but also providing fora uniformcompression of all heels operated upon by the dies, resulting in auniformity in the productv of the heel-compressing machine never beforesecured. As shown in Fig. 4, which represents the preferred form 'of myinvention, the extended part 12 is provided for only a portion of thelength of the lip; but, if so desired, the lip may be provided with anextended part for its entire length.

Having described my invention, what I claim as new, and desire to secureby Letters Patent of the United States, is-

1. Indies for compressing heels, means for *beveling a heel at the edgeformed by the breast and seat, and means for rounding the lower edge ofsaid beveled portion.
